I got FreeBSD 6.2-STABLE installed and running. I applied your patch
and rebuilt/installed the kernel. I went to the pvrxxx port and
cleaned it out, and made it again (with the addition of the case 0x5c:
in cxm_eeprom.c). I then went to kldload cxm. Output was like this:

---

tuner_type = 20

The WARNING line just stopped at the quote. I've rebuild the kernel
and the port a couple times, but no luck. Did I miss something when
updating to 6.2? or is this something to do with the driver?

Thanks!
